Abstract

In this paper, the mechanical behavior of lattice sandwich panel is studied using FEM. This lattice panel are composed of slender beams (diameter d=200μm) connected to each other, and can be manufactured easily by selective laser melting technique. In this study, the effects of lattice's microarchitecture, number of unit cell in xyz directions and the thickness of facesheet on the mechanical response (initial stiffness under tension and bending rigidity) are investigated.
